Claims

[Scope of utility model registration request]

A chute arranged at an angle to transport samples such as pieces of iron, a projecting light guide that irradiates light onto the sample being transported on this chute, and a sample of the light irradiated from this projecting light guide. It is equipped with a light-receiving light guide that receives reflected light from the film and a timing determining device that determines the measurement timing by detecting that the sample being conveyed on the chute has reached a predetermined position. A sample detection device in which the distance between the light guide and the timing determination device is set such that the shape detection position by the light emitting/receiving light guide is at the same position for each sample.
